12 Best Science Competitions for High School Students

If you are passionate about science, then you already know it’s a competitive space to be in.

One way of challenging yourself and seeing how you stack up against high-caliber peers is to participate in competitions! This is also handy for your scholar profile - for instance, the Common App has a section dedicated to any awards, honors, or recognition that you may have received. If you do have something to share, it’ll boost your profile because admissions officers love to know whether you are exceptionally good at something.

We’ve shortlisted 12 of the best science competitions ranging from research-based challenges to hands-on projects, to prestigious olympiads conducted at a regional, national, and even international level.

1. USA Physics Olympiad (USAPhO)

Like most science/math olympiads, the USAPhO has a regional-level exam that you need to score very well on, in order to qualify for the national Olympiad. For the USAPhO, you need to first attempt the F=ma exam.

The syllabus for which includes mechanics, including kinematics, statics, Newton’s laws, momentum and energy, oscillations, orbital mechanics, fluids, and elementary data analysis, as well as calculus-based questions. Based on your scores from the F=ma exam, you qualify for the US Physics Olympiad, the country's most prestigious competition for all physics enthusiasts.

As part of the USAPhO syllabus, you are expected to be familiar with basic concepts of physics as taught in high school, as well as some advanced understanding of the subject, which can help you perform better in questions that require application-based thinking. Apart from MCQ-based questions, you are also required to attempt long-answer formats that you must support with figures and diagrams.

To familiarize yourself with the F=ma exam, its rules, procedure, syllabus, and any extra details, check out our guide on the F=MA exam!

International Physics Olympiad

The International Physics Olympiad (IPhO) had its first edition in 1967 and sees participation from thousands of students each year. It is also held in a different country every year.

In order to qualify for the International Physics Olympiad, you must first participate in regional/national-level physics tests, which may vary based on your country of residence. If you qualify as one of the top finalists, you are sent to represent your country at the IPhO!

3. AMC 10/12

If you’re a high school student looking for a competitive experience in the field of mathematics, the AMC 10 and AMC 12 exams are opportunities you should keep an eye out for.

The syllabus of the AMC 10 covers mathematical concepts taught up until the 10th grade, while AMC 12 includes topics taught throughout high school, including trigonometry, advanced algebra, and advanced geometry, but excluding calculus.

Both the AMC 10 and AMC 12 are 25-question, 75-minute, multiple-choice examinations, and have two sets of questions, of which you can attempt either one (A or B).

Tip: You can find AMC 10/12 preparation materials here!


AMC10/12 A - November 10, 2023

4. U.S. Math Olympiad (USAMO)

An olympiad just as, if not more, competitive and prestigious as the USABO, UNSCO, and IPhO, the USAMO is hosted annually for all high school students. It invites some of the brightest of competitors every year, and 6 top scorers are trained and sent to the International Math Olympiad to compete with teams from other countries. In order to qualify for the USAMO, you must be one of the top scorers at AMC 10, AMC 12, and AIME.

Since USAMO is an invitation-only proof-type examination, you are expected to have a strong hold on mathematical concepts such as topics in algebra, geometry, number theory, combinatorics, probability, and methods such as induction and proof by contradiction.

Since exposure to proofs in high school is limited, you may receive a lower score than expected, but this should not deter you from battling it out with fellow high school students!

The exam is split into two 4.5-hour sessions, with you being given 6 questions to solve, without using a calculator.

IMO - International Math Olympiad

If you’re one of the top scorers at the USAMO, you are selected for the International Math Olympiad training camp, which usually involves rigorous preparation and testing to prepare the team that represents the US. You compete with over 20 countries at the IMO, and getting selected for the US Math Olympiad team is an extremely prestigious achievement.

You can take a look at the structure of the IMO, eligibility, sample questions, and more here.
